AbstractLow dielectric constant interlayer dielectric ( ILD) materials are required for the advanced silicon integrated electronics such as those in the ULSI era[3, 10]. We have investigated several such materials. In this paper the results of our investigations of the materials and electrical properties, processing ( to form ILD ), and applicability of a DuPont fluorinated polyimide are described and discussed. Weight loss, FTIR, and ellipsometric measurements have been carried out. The DuPont fluorinated polyimide thin film was observed to be thermally stable up to 450°C, which is monitored by using dynamic TGA with a ramping rate of 10°C/min or 5°C/min in N2 Ambient. Also MIPOS capacitor characterization, effect of temperature and moisture on these properties have been determined. The dielectric constant was observed to be as low as 2.5 and the refractive index is around 1.63, both being stable up to 450°C. However, the DuPont Fluorinated polyimide exhibited a flat band voltage shift on C-V curve after 400°C annealing in vacuum environments for 1 hr. Compatibility with copper as the interconnecting metal has been determined and discussed[8]. It is concluded that this polymer is a possible candidate for ILD application.

AbstractPorous low dielectric films containing nano pores (∼20Å) with low dielectric constant (<2.2), have been prepared by using various kinds of cyclodextrin derivatives as porogenic materials. The pore structure such as pore size and interconnectivity can be controlled by changing functional groups of the cyclodextrin derivatives. We found that mechanical properties of porous low-k thin film prepared with mCSSQ (modified cyclic silsesquioxane) precursor and cyclodextrin derivatives were correlated with the pore interconnection length. The longer the interconnection length of nanopores in the thin film, the worse the mechanical properties of the thin film (such as hardness and modulus) even though the pore diameter of the films were microporous (∼2nm).

A Sr-based metal–organic framework exhibits an intrinsic low dielectric constant after removing the water molecules. A low dielectric constant and high thermal stability make this compound a candidate for use as a low-k material.

ABSTRACTA modem VLSI device is a complicated three-dimensional structure that consists of multilayer metallization conductor lines which are separated with interlayer-dielectrics as insulation. This VLSI technology drives the IC device into sub-micron feature size that operates at ultra-fast speed (in excess of > 100 MHz). Passivation and interlayer dielectric materials are critical to the device performance due to the conductor signal propagation delay of the high dielectric constant of the material. Low dielectric constant materials are the preferred choice of materials for this reasons. These materials, such as Teflon® and siloxanes (silicones), are desirable because of their low dielectric constant (∈1) = 2.0, 2.7, respectively. This paper describes the use of a low dielectric constant siloxane polymer (silicone) as IC devices passivation layer material, its chemistry, material processes and reliability testing.
